I own a Netgear JNR1010 router with firmware version 1.0.0.18(latest version). When i telnet to the router, I am able to login using the default root password. I would like to change the root password, but I aM not able to do so.

My router runs Busybox 1.6.1. I tried using the passwd, chpasswd commands but none of these exist. I tried downloading the chpasswd file but could not make it as executable since there is no chmod command.
